### Public-Facing Changes - Add parameter to include hidden topics and services (not included by default) ### Description Adds the new parameter `include_hidden` which controls if hidden topics or services are advertised. From https://design.ros2.org/articles/topic_and_service_names.html#hidden-topic-or-service-names: > Any topic or service name that contains any tokens (either namespaces or a topic or service name) that start with an underscore (_) will be considered hidden and tools may not show them unless explicitly asked.
